CHARLES EDWIN HAMILTON, OF TROY, Y0.

IRONING- MACHINE.

Application filed June 2 8, 1921. Serial No. 480,980.

To all 'wltgm it may concern:

Be it known that I, CHARLES EDWIN HAM- ILTON, a citizen of the United States, and a resident of Troy, in the county of Rensselaer and State of New York, have invented certain new and useful Improvements in Ironing Machines, of which the following is a specification.

The invention relates to ironing or pressing machines of the type embodying a padded work support and a pressing iron, the two being relatively movable to each other; and it has for its object to provide a construction wherein the steam and moisture may conveniently and efficiently be removed from the padded surface. Apparatus of this type has been disclosed, for example, in U. S. Letters Patent No. 447,559 and No. 962,213. It has been found, however, that difficulty is experienced with the particular embodiments set forth therein, in view of the clogging of the perforations of the support by the textile covering material, so that the apparatus becomes substantially inoperative for the purpose intended.

The present invention has for its object to overcome the objectionable features of the aforesaid types in which the textile material or-pad employed is directly in contact with the support surface. To this end, the invention, contemplates the provision of an intermediate air chamber or free space so that the textile material can at no time come in contact with the actual perforated supporting surface.

In the accom anying drawings in which there is shown, y way of example, a cylindrical type of ironing machine of the aforesaid nature Fig. 1 is an elevation of the improved element of the ironing apparatus, with portions thereof broken away.

Fig. 2 is a fragmentary transverse section therethru and on an enlarged scale.

Similar characters of reference designate corresponding parts thruout the several views.

Referring to the drawings, 10 indicates suitable bases or stands in which is rotatably mounted a hollow support member as the cylinder 11, although do not wish to be confined to the particular shape of the support member shown. The said support is designed to cooperate in well-known manner with a suitable ressing iron or member, (not shown) to e ect the ironing of various articles; and a pad 12, composed of various layers of textile material such as muslin, cotton cloth, felt and the like, is provided over the support in manner hereinafter set forth. It is the object of the invention to There is provided, furthermore, over the pe-' 'riphery of the cylinder and beneath the covering, resilient means affording an intermediate free space or air chamber 14. The

interior of the cylinder is, moreover, con-- nected thru a suitable tubular shaft 15 with exhausting apparatus as the pump 16.

The resilient separating means may eonsist of a plurality of coil spring members 17 such asare disclosed in my prior U. S. Patent No. 1,054,507, granted me the 25th day of February, 1913, as well as in my co-pending application Serial No. 460,696, filed April 12th, 1921. These springs are preferably retained between end ca s 18 which are, furthermore, centrally per orated. The series of caps are secured to and arranged about the periphery of the cylinder 11 to cover same, as shown, and in manner such that the perforation of a lower cap adjoining the periphery of the cylinder will register with a perforation 13 or groove 13 thereof. Over the tops of the caps is provided the ad or covering 12 of textile material, whic may consist of various layers to suit the character of the work.

During the 0 eration of ironing, any moisture or steam liberated or generated by the application of the hot iron will be drawn toward the interior of the cylinder and removed therefrom by the pumping apparatus 16, the moisture readily passing not only thru the caps and the spaces between same but also thru the perforations 13 and ooves 13' of the cylinder to its interior. y this means, a pressing surface is afforded which will be maintained substantially dry thruout the operation and thus result in more eflicient and satisfactory operation.

I claim 1. In an ironing machine, in combination: a rotatable roll, pad supporting means mounted upon said roll and composed of a plurality of individual and adjacent resilient members disposed over and substantially covering the surface of said r011, one end of each of said members terminating at the roll and being thereto secured and the other end thereof terminating away from the roll and being out of contact therewith and unsecured thereto, an ironing pad mounted over said supporting members, and means to circulate air thru the free space afi'orded by the resilient members'to remove moisture from the pad.

2. In an ironing machine, in combination: a rotatable roll, supporting means mounted upon said roll and composed of a plurality o helical-adjacent springs radially disposed over and covering the surface of the roll; a fabric ironing pad mounted directly over said supporting springs, the latter affording an intermediate free space between said pa and the surface of the roll; and means to circulate air through the free space to re-- move moisture from the pad.

3. In an ironing machine, in combination: a hollow cylindrical and perforated rotatable roll having a spiral groove over its surface connecting the perforations therein, pad supporting means-mounted upon said roll and composed of a plurality of individual and adjacent resilient members disposed over and covering the surface of the roll, a fabric ironing pad mounted directly over said supporting resilient members, the latter affording an intermediate free space between said pad and the surface of the roll, and means to withdraw moisture from the said pad through the interior of the roll through said grooves andperforations.

Signed at New York, in the county of New. York and State of New York, this th day of June, A. D. 1921.
